高效沉淀池在熄焦废水处理中的应用

Application of high efficiency sedimentation tank in waste quenching water treatment

介绍了一种处理熄焦废水的新型沉淀池。其特点是高径比大,占地面积小,表面负荷高,污泥悬浮层厚。利用污泥回流原理,实现以泥代药,充分发挥药剂的混凝作用,减少加药量,稳定处理过程,提高出水水质。

Introduction is made to a new type of sedimentation tank used in waste quenching water treatment,with the characteristics of high slenderness ratio and small land occupation,which features in high surface load and thick suspended sludge layer inside.Making use of return sludge as the substitute for coagulant,the sedimentation tank gives full play to coagulation effect and reduce the amount of added coagulants,helping to stabilize the water disposal procedure and enhance the quality of discharge water.
